Abstract

Thin films of diacetylene derivatives with carbazol substituents have been prepared by epitaxial growth on different organic or inorganic substrates. Both structural aspects and optical properties have been investigated in order to obtain high cubic polarisability x(3) in well oriented assemblies of conjugated polymeric chains. Using thin film evaporation technique under high vacuum, we are able to prepare optical films of high quality, perfectly bioriented on some alkali halide crystals and monooriented on various organic crystalline substrates. Third harmonic generation (THG) measurements on such films confirm the large scale orientation of polydiacetylene crystals locally observed by electron microscopy.
